UNITED STATES PATENT HERMANN SGERODER, Q1 NEW YORK, N, Y.

1'0 all whom it may concern:

Be it known that I, HERMANN Sonnonnn, a citizen of the United States,residing at New York in the county of New York and State of new anduseful Improvements in'Resonance- -Chambers for Sound-ReproducingAppation.

This invention relatesto improvements in sound reproduction apparatusand more articularl to an improved resonance ox,

ratus, of which the following is a specificasound. 0 amber and soundoutlet for all types" provide a resonance box, sound chamber or basin soconstructed as to ada t it to contain a volume of water or other 'iquid1n order to produce the advantageous results above mentioned.

The inventionalso has as its object to provide a resonance chamber andsound outlet which will add greatly to the appearance of the instrument1n connection with which it is employed. l

In the accompanying drawings:

Figure 1 is a perspective view of a cabinet phonograph, equipped withthe resonance chamber and sound outlet embodying the invention Fig. 2 isa horizontal sectional view throu h the forward portion of the cabinetandi ustrating the forward portion of the said chamber inplan;

The resonance chamber, embodyin the present invention is clearly showniniig', 4 of the drawings. and the said chamber. is indicated in generalbythe numeral 5 and comprises a flared body 6 havingside walls 7, a

co the cabinet 1 is open at the upper top wall 8, and a bottom wall 9.The chamher 5 is of general recta'n lar form in cross section but itsside we s 7 converge in a rearward direction and its top wall 8 isinclined' downwardly and rearwardly so that the chamber is of greaterdimensions at its delivery end 10 than at its inner end. The said Wallsof the chamber at the inner end thereof merge and form an u neck 11tapered in the direction of its upper end and connected in any suitablemanner at its said end with the lower end of the tone arm 2. Thedelivery resonance chamber is disposed a proxiinately'fiush with theopen side 4 of t ecabinet 1 as clearly shown m Fig. lot the draw ing's,or it may rotrude in an ornamental.

manner upwar y or downwardly away from the said front and while the saidend of the resonance box is illustrated in the drawings as left entirelyopen, it will be of the ordinarymeans partly closing the same.

As previously stated, the resonance box pwardly curved end 10 of the ofthe present invention is so constructed that it may contain a volumeofwater or other li uid which will serve as a medium for mo ulating thereproduced tones and uality. In-order that the resonance cham er orsound outlet may beso adapted, its bottom wall 9-is disposedhorizontally and the said wall is extended forwardly beyond the deliveryend 10 of the box to form the bottom 12 of a basin indicated in generalby the numeral 13. Likewise the bottom wall 12 is extended laterally asat 14 and at its lateral portions'is likewise preferabl extendedrearwardl as at 15 so that the ottom of the basin will not only extendin front of the cabinet 1 but also partly at the sides 4 shown in Fig.

thereof. The purpose of this construction will presently be made clear.The numeral 16 indicates the upright wall of the basin which wall has afront portion 17,- side portions 18 which extend at the outer edges ofthe respective portions 16 of the bottom ofthe basin, and other portions19 which extend opposite the portions 18 and around the forward cornersof the open front of the compartment 3 as at 20 and are joined to theside walls 7 of the resonance chamber. Thus the basin extends not onlywithin the interior of the compartment 3 but also across the front ofthe said compartment and consequently across the front of the cabinet,and also partly at the sides of the cabinet.

The resonance chamber will preferably be made of glass although anyother material or combination of'materials may be employed for thispurpose and it will be'understood that the exposed portions of the .saidchamber may be suitably ornamented so as to add to the attractiveappearance of the cabinet of the instrument as a whole. In the lateralportions of the basin, and if desired even in the front portion thereof,flow ers may be arranged so as to further add to the appearance of theinstrument, the basin beingfilled to any desired level with water or anyother liquid as best shown in Figs. 1 and 3 of the drawings.

In order that the liquid may be drawn of? whenever desired, a drain pipe20 is fitted through the rear end of the basin as best 3 of the drawingsand leads through the rear wall of the cabinet 1 and is provided withany suitable type of fancet21.'

As before stated, cut flowers or aquaticplants may be arranged withinthe lateralor even the front portion of the basin, and also ifi desired.various aquarium ornaments ma be arranged within the basin..-

ile as stated it is preferable that the I neeaeoa as reproduced aremodulated in the same manner as are other musical sounds when heardacross a body of water.

Having thus described the invention, what is claimed as new is:

1. A resonance chamber for sound reproducing apparatus having in itslower por- By reason tion a bottom, and a wall completely surroundingthe bottom and providing a basin adapted to contain a volume of liquid.

2. A resonance chamber for sound reproducing apparatus having a liquidcontainin basin forming its lower portion, the said basin extendin to apoint in advance of the delivery end 0 the chamber.

3. A resonance chamber for sound reproducing apparatus having a liquidcontaining basin forming its lower portion, the said basin extending toa point in advance of the delivery end of'the chamber and being alsoextended laterally. 4. A resonance chamber for sound reproducingapparatus having bottom, side and top walls, the bottom wall beingextended beyond the delivery end of the chamber, and an upright wallsurrounding the extended portion of the bottom wall-whereby to'provide aliquid containing basin.

5. A resonance chamber for sound reproducing apparatus, having a lowerportion constructed to contain a volume of liquid, and valved meanswhereby the liquid may be drained from the said chamber.

In testimony whereof I afiix my signature.
